To all whom it may 001mm:

Be it known that we, CHARLES B. YOUNG and CHARLES J. CAsrAR, citizens of the United States, and residents of Pittsburgh in the county of Allegheny and State o Pennsylvania, have made a new and useful Invention in a Store-Front Construction, of which the followin is a specifica-tion.

The invention re ates to store front constructions. It has for its principal object the provision of an improved construction which permits of the setting of the lglass from the-front in such manner, that there is no danger of breaking the glass and wlth a minimum amount of elfort on the part of the workmen. It has for its further object the provision of an improved cover plate construction in which the number of holding screws is reduced to a minimum andk which is held very securely, but which atv the same time, presents none of the difficulties as to removal after a long period of time, such as are present with certain of the so-called screwless types of cover plates. One embodiment of the invention is illustrated in the accompanying drawings where- Figure 1 is a front view of the assembled construction with portions of the glass and cover strip broken away to more clearly disclose the construction. Fig. 21s a perspective view showing the construction of one of the clamps with the glass and cover strip removed. And F ig. 3 is a section on the line III-III of Fig. 1.

Referring to the drawings, the members 1 and 2 are arts of the window framing in which the glass plate 3 is seated, the part 1 constituting an inwardly rejecting ledge in opposition to the rear ace of the glass and the part 2 constituting a laterally extending ledge in opposition to the edge of the glass sheet. The glass sheet is supported by means of the usual wood blocks (not shown), the pressure of the holding devices as later described not being suicient to sup# port the weight of the glass. The two ledges 1 and 2 are protected by means of metal sheatliin of the angular cross section indicated infig. 3, the upright portion 4 being referred to as the back strip. and the lateral portion 5 being referred to as thebase strip as these parts might be separate'members and the part 4 mi ht be dispensed with, although the preferre and usual arrangement is to employ the construction just as illustrated so as to ive a maximum amount of protection to t e wood members 1 and 2.

At its outer edge, the 'bottom strip 5 is provided with a flange 6 spaced away from the ledge 2 to provide a recess for the edge of the cover strip as later described. Spaced at intervals along the base strip are the angular brackets or clips 7, each having a flange 8 in opposition to the back strip and a flange 9,'the .outer ortion of which is'oifset, as indicated in igs. 2 and 3 to provide a space for the lower ends of the screws 10, the extreme outer edges of the flanges 9 being supported upon the flanges 6 of the base strip 5. The anges 8 of the brackets cr-clips are clamped a ainst the back strip' vis preferred, as the screws 11 perform the double function of holding the sheathing,

comprising the members 4 and 5 in -position the brackets 7 in position.

and of clampin the brackets or clips 7 is Upon each o mounted an angle clamp or bracket 12, such bracket comprising a clam ing iiange 13 and the laterally extendin dhnge 14, which rests upon the bracket 7. The clamp is preferably provided with a slotted portion 15 lying in the flange 14 and a slotted portion 16 lying in the flange 13, the 'slot 16 being wide enough to permit the head'of the holdinfr screw 10 to slide therethrough, thus provi ing in effect a bayonet joint, permitting application and removal of the clamp without removing the screw 10. The opposing faces of the flanges may be, and preferably are, roughened, so that when the screw 10 is tightened, there is less danger of the clamp slipping. .As heretofore referred to, 'the spacing of the flange 9 away from the cover strip 5 provides room for the lower end of the screw 10 so that vit may be tightened without coming into contact with the base strip.

The upper edge of the clamping ilange 13 is turned back upon itself as indicated at 16 and provided with a threaded perforation 17. The cover strip 18, preferably of sheet copper, is formed at one edge with the flange 19 adapted to fit beneath the flange 6, and at its other edge, is turned laterally pat 20 so as to fit over the clamps and entirely and pressed up against t cover them. The cover strip is secured in position at its upper edge by means of the screws 21.

In setting the glass 3, it is first placed in position in the sheathing 4, 5 supported at suitable intervals by small wood blocks. The clamps 12 are then put into position e glass and the screws 10 tightened. This procedure prevents any undue pressure belng a plie to the glass by the c amps 12, since t e application of the screws 10 does not tighten the clamps. There is, therefore, no danger of breaking the glass from this cause, such as sometimes occurs with a clamp arranged so that tightening of the screw holdingI it forces the clamp against the glass. The

cover strip is then applied by hooking its iiange 19 beneath the flan 16 and applying its up er edge over t e clamps as indicated in ig. 3, after which the screws 21 are put in place. The labor of applying the cover strip is thus relatively shght, as screws need to be apsplied only at one edge. The cover strip is a easily removed after a long period of service, since there is no diiiiculty in removing the screws 21, after which the upper edge of the cover strip can be sprung back permitting a grip upon the strip either by the hands of the operator or by a tool such that the ange 19 may be loosened without diiiiculty, even though it has tightened in position due to corrosion or other causes incident to the passage of time. The glazing of the window can be accomplished by one man working from the outside, as no cooperationis required from the inside of the glass as is the case in many forms of setting. Other advantages incident to the cheapness and sim licity of the construction and the ease wit whlch it ma be applied and removed from position an its extreme safet will be readily apparent to those skilled 1n the art.
